WARREN M. BRINKRHOFF, OF`AUBURN, NEW YORK.

LUBRICATOR.

SPECIFICATION 'forming part of Letters Patent No. 261,661, dated J'uly 25, 1882.

Application filed une 27, 1882. (No model.)

To all whom it may concern:

Be it known that l, WARREN M. BRINKER- HOFF, a citizen of the Unit-ed States, residing at Auburn, in the county of Cayuga and State of New York, have invented new and useful Improvements in Lubricators, of which the following is a specication. l

This invention relates to lubricating 1nech anism for hangers, journals, axles, &c., and all kinds of machinery in which the lubricant is drawn from the oil-cup by capillary attraction or by permeation through a conductor composed ot' some light porous material.

Heretofore the oilcup has been made separate from the said conductor.

It is the object of this invention to simplify such construction by forming the oilcup in one piece, with the conductorinclosed, there* by reducing cost and bulk, rendering the device more convenient and capable of being easier applied, effecting a more ready saturation of the conductor with the lubricant than heretofore, and avoiding the escape of oil between the oil-cup and the conductor.

In the annexed drawings, which illustrate my invention, Figure 1 represents in perspective my combined oil cup and conductor, with an auxiliary Wick inclosed in the latter. Fig. 2 is a view similar to Fig. 1,but with theauxiliary wick omitted. Fig. 3 is a transverse ver tical section through Flg. l, with the cover of the oil-cup tted thereto. Fig. 4 is a like sectional view of Fig. 2, with the cover in place. Figs. 5 and 6 show the conductor made separately from the oil-cup, as in Letters Patent granted to me June 13, 1882, No. 259,470.

Referring by letter to the said drawings,`Ain dicates the conductor,which consists of a block of some light porous wood o'rother suitable material, for conducting the lubricant from the oil-cup to thejournal. This block is concaved at one end, as at a, orotherwise fashioned, so as to tit or bear against the journal to be lubricated, and in its opposite end it is provided with a chamber, B, which constitutes the oil cup or reservoir for containing and supplying the lubricant. This chamber extends a portion of the length of the block, and can be closed by a suitable cap or cover, 0,'Which in Figs. 1 and 2 is represented as being detached and in Figs. 3 and 4 fitted to the chambered end of the conductor.

In Fig. 1 I have showlethe conductor formed with a bore or perforation extending from the bottom ot' the oil cup or chamber to the concaved bearing end of the conductor, and in this bore I have arranged a wick, D, of some suitable fibrous material. This wick constitutes an auxiliary means for conducting the oil from the cup to thejournal, it being under stood that more than one of these bores and wicks can be employed, if desired.

seen that it is not necessary to increase the diameter ot' the block in order to provide the oil-cup.

As the walls ofthe oil-cup are integral with the body ofthe conductor, the oil absorbed by said walls will gradually enter the conductor, and thus supply the same more eliective'ly than These blocks can be cheaply made, and it will beA if the two were made separately, and the es- K cape of oil between t-he conductor and the oilcup prevented.

This combined oil cup and conductor can be arranged above the journal and fed downward by spring-pressure, 0r allowed to descend by gravity as the bearing-surface of the conductor becomes worn, or the same are arranged un der or at the side of the journal and fed forward by spring-pressure or other suitable mechanical means, although the former method is the preferred one. Where the conductor is made solid the oil will be drawn or creep through the same by capillary attraction or by permeat-ion, and thus continuously supply lubricant to the journal or part to be lubricated.

Having thus described my invention,whatI claim is- 1. As a means of lubricating hangers, journals, axles, Ste., an oil-conductor made of wood or other suitable material, and provided with a chamber integral therewith for" holding a supply of oil, substantially as described.

2. A combined oil cup and conductor for lubricating hangers, journals, axles, Ste., con sisting of. a block of wood or other suitable material, having one end constructed for bearing against the journal, and provided on its opposite end with an oil-chamber formed ining extending from-the oil-chamber to the end tegral with the conductor, substantially as dewhich bears against the journal, substantially scribed. as described.
